Photos: Pi Day Celebrations at 2015 SXSW Festival

Math enthusiasts celebrate Pi Day every year on March 14, to honor the mathematical constant that represents the ratio of a circle's circumference to its diameter. This year's event, however, happens just once in a century. Today, March 14, 2015, at 9:26 a.m. and 53 seconds, the date and time...

What Are Quadratic Equations?

In mathematics, a quadratic is a type of problem that deals with a variable multiplied by itself — an operation known as squaring. This language derives from the area of a square being its side length multiplied by itself. The word quadratic comes from quadratum, the Latin word for square....

In geometry, an object exhibits symmetry if it looks the same after a transformation, such as reflection or rotation. Symmetry is the underlying mathematical principle behind all patterns and is important in art (used in architecture, pottery, quilting and rug making), mathematics (relating to geometry, group theory and linear algebra),...

Properties of Pascal’s Triangle

Pascal’s triangle is a never-ending equilateral triangle of numbers that follow a rule of adding the two numbers above to get the number below. Two of the sides are “all 1's” and because the triangle is infinite, there is no “bottom side.” It is named for Blaise Pascal, a 17th-century...

Where's the Proof in Science? There Is None

This article was originally published on The Conversation. The publication contributed this article to Live Science's Expert Voices: Op-Ed & Insights. UNDERSTANDING RESEARCH: What do we actually mean by research and how does it help inform our understanding of things? Those people looking for proof to come from any research...

What Are Logarithms?

A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. Because logarithms relate geometric progressions to arithmetic progressions, examples are found throughout nature and art, such as the spacing of guitar frets, mineral hardness, and...

Pi, Anyone? The Secret to Memorizing Tens of Thousands of Digits

Every year, math enthusiasts celebrate Pi Day on March 14, because the date spells the first three digits (3.14) of pi, or π, the mathematical constant that represents the ratio of a circle's circumference to its diameter. This year, the event is even more special because, for the first time...

What Is Calculus?

Calculus is a branch of mathematics that explores variables and how they change by looking at them in infinitely small pieces called infinitesimals. Calculus, as it is practiced today, was invented in the 17th century by British scientist Isaac Newton (1642 to 1726) and German scientist Gottfried Leibnitz (1646 to...

What Is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles. Trigonometry is found all throughout geometry, as every straight-sided shape may be broken into as a collection of triangles. Further still, trigonometry has astoundingly intricate relationships to other branches of mathematics, in particular complex...

A Woman Finally Wins Top Math Prize 'Fields Medal'

For the first time in history, the Fields Medal — the equivalent of the Nobel Prize for mathematics — will be awarded to a woman. The award will go to Maryam Mirzakhani, an Iranian mathematician and professor of mathematics at Stanford University. Mirzakhani and three other mathematicians will be honored...
